Subject Re: [POLL] Who still uses Java 7 with Flink ?
Date Thu, 23 Mar 2017 11:12:36 GMT
Robert,

Thanks for the report. Shouldn’t we be revisiting this decision at the beginning of the
new release cycle rather than near the end? There is currently little cost to staying with
Java 7 since no Flink code or pull requests have been written for Java 8.

Greg
